[PATCH 07/11] t7508: make test "set -e" clean

[Junio C Hamano <gitster@pobox.com>]

In order to catch mistakes like misspelling "test_expect_success",
we would like to eventually be able to run our test suite with the
"-e" option on.

This test tries to unconditionally clear a few configuration
variables, but "git config --unset VAR" fails if VAR is not set.
Work it around by telling the shell that failures from them are OK.
